I received a copy of this book from Goodreads.
While my own political leanings tend to be somewhat left of center, I grew up in a Republican/conservative household and used to lean much further right as a young person. Of course, this was back in the 1990's before the Republican party meandered wildly to the far-right. I do enjoy a healthy debate and still do vote for some conservatives in elections, so I'm up for reading anything to do with politics as I like to books that might pull me out of my comfort zone and preconceived notions to look at things with a fresh viewpoint.
I tried to read this book with an open mind. Quite honestly, replace the words conservative/Republican with liberal/Democrat and it could be about any political party complaining about the other. However, that's where the similarities ended. This book was much more about "the sky is falling!" than coming up with a great plan for conservatives to beat those evil leftists. Basically, Democrats are bad, they're out to overthrow all things good and moral in this country, we need to rise up and take things back if we're going to get Trump reelected in 2020. If this is your line of thought, you are going to love this book. If you tend to be anywhere in the "middle ground", lean liberal or even Libertarian, you will most likely close the book and shelve it somewhere next to the Ann Coulter and Rush Limbaugh books that you bought over the last decade and still roll your eyes at to this day.
In short: Today's "Republicans" will enjoy this book. Anyone else will simply find it a distraction from the impeachment proceedings currently on tv.
